Be it known that l, (Tommi-Ins CORCO- RAN, a. citizen of the ll nited cs. residing in borough. of the Bronx. in the county of the Bronx, city and State of New liloik, have invented certain new and usetiful. improve ments in lllypewi'iting lvlaiizhincs. ct which the following is s specification.

This invention relates to signals for type- Wiiterssuch are used to Willil lill? OPQTJZI- live of the approach to the end of a line of writing; and an object of the intention is the improvement gen rally Oi the operating; means flu such nels. and also the provision of a signal that will ode uute Warn that the end on" the line of Wnfng; is

near.

lo the llnderwooiil. typewriter, to which my improvements are upplierh it is custoi'nary to lock the typekcys at the end of the line oi wi'iting and also to soundv the hell. a few letter-spaces prior to that space which the key-lock hecomes effective. such signal-bell acting as a warning to the open ative that the end of the line is about to he reached. It may sometimes happen that the operative may forget that the signal has been sounded. as it is customary to sound it but once, and may attempt to Write a ord of more letters than there ore letter-spaces he tween that letter-space at which the signal sounds and the letter-space at which the keys become locked.

A feature of the present invention, therefore. relates to the provision of means for giving signal such as the sounding ot a hell. :iteach of u succession of letter-space positions of the carriage next preceding that letter-space at which the hey-locking means becomes operative in order that the power to operate the signal-hell may he ejtliciently employed, said power preferably taken directly from the spring which impels the carriage in its letter-spacing movements. Preferably. too, the helLsounding means 18 normally disconnected from th power means that actualcs it, and connections provided whereby the typewriter-cairings renders the hell-soundiu' means etiectii'e on reaching; a prod-e crinincd. hut variably a justalole. lei -spaco position, the coifiriu holding the belhsoundinu means cli'ccti 1o 2.

a suf ic icnt time, to permit the hell to he sounded a succession of times as the ca triage continues to soece. The signal-actuating will hereimprovements.

.. iq'ui'e 2 2 front elevation of the left hand portion of the typewritef-ti aine and carriage. Figure is a detail showing a. bell-hammer in raised position. under the action of a. p n on the pin-disli; and t Figure Tlis a perspective View, showing; the signal-actuating; mechanism in normal position.

Refer to the (liaWings and particularly to Figure 1 type-lieys l, pivoted at 2. are connected through intermediate levers 3 to type-hers 4:. each oi which on depression of key-leven is adapted to be driven up Wardly and rearwardly against the front face 03'. u. platen 5, supported. in a; carriage (-3. The can" go supported in the tear on a bar 7, on which it slides, and it is supported at its forward portion on a rod 8, by antifi'iction roller 9 connected to the typewriter- L'XLTIlEgG and eng"aging the rod 8. The usual spring-drum 10 is provided, in which is ascoiled spring connected to the carriage at 11, for impelling' the some forwardly. Connected to the carriage is a toothed ha r 12, engegin u pinion 13, to which is connected an escapelnent-wheel 14;. with which engage escapemeut dogs 1! and 16, which are moved into and out of engagement with the escupercent-Wheel, under control of the keys by means of a universal escapeinent-fmme 17., as is customary in the Underwood machine.

The typekeys 1 have formed thereon projections 18, which are adapted to be engaged by a locking; our 19, forming part of a cradle, said cradle including end levers 20, of which the -i ht-hand one is shown in Figure 1, and a supporting i'od 21. on which the cradle is mounted. for pivotal movement. The locl-:- ing but in ay be operated to lock the keys, by means, usually provided in these machines, said means including a car-o 22. carried by the typewriter-carriage; said calm being adapted to engage and depress a member 23, which, when depressed, acts to rock a shaft 24, mounted for pivotal movement. The shaft 24 has a depending arm 25, carrying at its end a pin 26, adapted to engage an arm 27, rigid with the rod 21, to rock the cradle and move the bar 19 underneath the projections 18, to thereby lock the keys against depression. As shown in Figure 2, the member 23 has a cam-surface 28, which is first engaged by the cam 22. As the carriage continues its stepby-step movement, the cam 22 depresses the member 23, said member being provided with a flat portion 29, and, when the cam 22 is in engagement with this portion 29, the memier 23 is'held in its depressed position. During this time, the shaft 24 has been rocked, but not sufficiently for the pin 26 to engage the arm 27. Therefore, the keys are not locked at this time. As the carriage continues its .step-by-step movement, the cam 22 engages a projection 30 on the member 23, and further depresses the same, resulting in a further rocking of the shaft 24, and, during this further rocking, the pin 26 engages and moves the arm 27, to render the key-lock effective. It will thus be seen that the member 23 and also the shaft have each an initial and a final movement, and it is this initial movement that is availed of to control means to give adequate warning to the operative that the end of a line of writing is about to be reached, and that the keys are about to be locked.

In the present embodiment of the invention, this warning means preferably consists of a bell 31, and means for operating the bell at several successive letter-space positions of the carriage just prior to the operation of the key-look. Preferably, I provide a frame, consisting of a pair of levers 32 and 33, connected at their lower ends by a sh aft 34, pivotally mounted between the levers. The levers at their upper ends are pivoted in abracket 35, connected to a portion 36 of the typewriter-frame. Pivotally mounted. on the shaft 34 are tappets 37'and 38, and connected to each tappet is a bell-hammer Springs 40, one connected to each tappet below the shaft 34. normally urge the ham mers towards the bell, but they are held from actual contact therewith by lugs 41, one lug projecting from each of the levers 32 and 33, these lugs engaging the tappets under action of the springs 40. it will, of course, be understood that the hammer-arms are sufiiciently resilient, to enable the hammers to strike the bell. when the tappets are tripped. Power for tripping the tappets, to thereby operate the line-signal-bell, is taken directly from the carriage-spring, and, for this purpose, a disk 42 is connected to the carriage-drum by means of studs 43. The disk 42 is provided with pins 44, projecting from each face thereof, the pins on one face the hammers.

Normally, the frame, carrying the tappets, is in the position shown in Figure'4, with the tappets out of range of movement of the spring thus constitute actuating means for v pins on the disk, so that, during the major so portion of the line writing, no signal is sounded. However, when the carriage approaches the end of the line of writing and the cam 22 depresses the member 23, means are provided for rendering the pins effective to actuate the tappets, to operate the signal. This means preferably consists of a slide 45, having a pin-and-slot connection at 46 with the depending arm 25. Said slide 45 is guided. by pins 47 engaging slots in the slide,

one of which is shown at .48, Figure 4, and said slide at its end remote from the depend ing arm is provided with a cam 49, which engages an arm 50, connected to, or forming part of, the lever 33, said lever 33 otherwise being identical with the lever 32. Movement of the slide acts to move the leverframe, and thereby the tappets into the path of movement of the pins 44, the tappet 37 engaging the pins on the right-hand side of the disk, as viewed in Figure 4, and the tap pet 3S engaging the pins on the left side thereof. Therefore, as the disk 42 moves step by step, concomitantly with the stepby-step movement of the typewriter-can riage, the bell-hammers will be alternately tripped, and'the bell will be sounded at each letter-space during the time the tappets are in operative position with respect to the actuating pins 44; and it will be seen that this engagement will be maintained while the cam 22 is passing over the surface 29 of the member 23. As the carriage moves on, the cam 22 engages the projection 30, moving the depending arm into its final position to lock the keys.

l ariations may be resorted to within the scope of the invention, and portions of the improvements may be used without others.

Having thus described my invention, ii.
